Wood Stove Venting Kits

Relining a masonry chimney or connecting a new wood stove to an existing flue means sourcing the right liner, the right diameter, and every hardware component in a single order. A mismatched flue collar, an undersized liner, or a missing storm collar turns a straightforward installation into a costly return. A complete wood stove venting kit removes that risk by bundling the liner, end caps, and all required hardware into a single, factory-matched package.

A wood stove venting kit includes a flexible stainless steel chimney liner, top and bottom end fittings, and all hardware for a complete chimney reline. These bundles differ from individual stovepipe sections, which connect the stove to the wall and are covered separately in the wood stove pipe kit. Fire Pit Surplus carries UL listed chimney liner kits for wood stove and pellet stove installations, with 316L stainless steel as the standard material across the lineup.

Why Choose a Wood Stove Venting Kit

  • Complete Hardware, One Order: Every kit ships with the liner, top plate or anchor plate, end caps, storm collar, and termination cap included. No separate hardware sourcing, no compatibility guesswork between components.
  • 316L Stainless Steel as Standard: The 316L grade handles the higher acidity and temperature cycling of wood and pellet stove exhaust better than 304 SS. All liner kits in the lineup use 316L for long-term durability against creosote byproducts.
  • Sized for All Common Flue Collars: Kits are available in 5-inch, 6-inch, and 7-inch inside diameters, covering the flue collar sizes found on the majority of residential wood stoves and pellet stoves. The 6-inch diameter handles most wood stoves rated up to 2,100 sq ft.
  • Separate Wood Stove and Pellet Stove Configurations: Pellet stove venting uses 3-inch to 4-inch PelletVent, not the flexible liner in a standard chimney liner kit. The listing pages identify which kits are approved for solid fuel, pellet fuel, or both, so buyers can confirm compatibility before ordering.

  • Flexible design navigates offsets in existing masonry chimneys

Best Premium Stainless Steel Chimney Liner Kit

Olympia Forever Flex Chimney Liner Kit 6"

Olympia Forever Flex 6 inch stainless steel chimney liner kit

The Olympia Forever Flex is the premium alloy pick in the 6-inch category, using 316Ti stainless steel for superior resistance to the sulfuric acid condensate that wood combustion produces over time. It is offered in 25-foot and 35-foot lengths with a tee-kit or insert-connector configuration, making it the most adaptable 6-inch liner kit for both open-fireplace and insert installations.

  • 6-inch diameter; 316Ti stainless steel liner; 25 ft or 35 ft length options available

Best Long-Run Chimney Liner Kit

6"Ø X 35' Stainless Flex Liner Kit for Inserts VOLKI-635

The VOLKI-635 is the 6-inch long-run kit for two-story homes and taller masonry chimneys where a 25-foot liner falls short of the full run from insert connection to rooftop termination. The smooth-wall interior reduces draft resistance compared to corrugated designs, supporting stronger natural draft on chimneys where length or offset would otherwise reduce draw.

  • 6-inch diameter; 35-foot smooth-wall flexible 304L stainless steel liner for inserts
  • Includes liner, top plate, clamp, connector pipe and installation hardware
  • Smooth-wall interior reduces draft resistance on longer chimney runs

 

 

What to Look for in a Chimney Liner Kit

Liner Diameter and Flue Collar Match

  • Match the liner to the stove's flue collar exactly: A 6 inch chimney liner is the standard for stoves with a 6-inch flue collar. Flue cross-sectional area should not exceed twice the stove's collar area; an 8-inch liner on a 6-inch collar stove creates a column of cool air the stove cannot sustain draft through.
  • 6-inch is the standard for most wood stoves: Stoves rated for 1,000 to 2,100 square feet almost universally use a 6-inch flue collar. The 6 inch stainless steel chimney liner kit covers the majority of residential installations. Larger units above 80,000 BTU may require an 8 inch chimney liner kit sized for large whole-home systems. Confirm the spec plate before ordering.
  • Pellet stoves use different sizing: A pellet stove venting kit uses 3-inch to 4-inch PelletVent, not the 5- to 7-inch flexible liner in this category. Ordering the wrong type is the most common sizing mistake in venting installations.

Liner Material and Fuel Type Approval

  • 316L stainless steel for wood and pellet combustion: Wood and pellet combustion produces sulfuric acid condensate that corrodes 304 SS over time. The 316L grade includes molybdenum for acid resistance. All liner kits on this page use 316L as standard; confirm NFPA 211 compliance on the product listing for code-documented installations.
  • Flexible vs. rigid liner: Flexible liner navigates existing masonry chimneys with offsets and bends. A rigid liner is reserved for straight, unobstructed flue paths and is not compatible with chimneys that have elbows or angle changes. Nearly all residential relining jobs use flexible liner.
  • Check fuel approval on the label: Some liner kits are approved for gas appliances only and are not rated for the higher temperatures of wood combustion. Confirm solid fuel approval before ordering for a wood stove or pellet stove installation.

Kit Completeness and Hardware Inclusions

  • Confirm what the kit includes before ordering: A complete stainless steel chimney liner kit includes the liner, top plate or anchor plate, storm collar, termination cap, and locking band. Kits sold as "liner only" require separate hardware orders and add cost. A wall thimble is installed separately where the stovepipe passes through a combustible wall.
  • Rockwool insulation for exterior chimneys: An insulated chimney liner kit adds rockwool wrap around the flexible liner, reducing heat loss in exterior masonry and metal chimneys where the liner would otherwise cool too quickly to sustain draft. For interior chimneys in a heated home, standard uninsulated liner is sufficient.
  • Length options and on-site trimming: Most flexible liner kits are sold in standard lengths (15 ft, 20 ft, 25 ft). Flexible liner can be trimmed on-site with tin snips. Measure the chimney height before ordering. A liner that is short by two feet cannot be extended, only replaced.

 

 

Types of Chimney Liner Kits

Standard flexible chimney liner kits

Are the most common wood stove chimney liner kit purchase scenario: a 316L stainless steel liner in the correct diameter, shipped with all end hardware for a complete masonry chimney reline. They suit interior chimneys in the majority of residential wood stove installations. The liner navigates the slight offsets common in older masonry construction, and the included hardware covers a standard top-and-bottom termination without additional purchases.

Insulated chimney liner kits

Add a rockwool blanket wrap around the flexible liner for exterior masonry chimneys and metal factory-built chimneys where the liner surface cools too fast to maintain draft pressure. Cold liner walls cause condensation, accelerate creosote buildup, and reduce draft. If the chimney runs along an exterior wall or passes through an unheated space, an insulated chimney liner kit is the correct product type.

Pellet stove vent kits

Use 3-inch to 4-inch PelletVent pipe, not flexible liner. Pellet stoves produce a lower-temperature exhaust with different combustion byproducts than wood stoves, and PelletVent is engineered for that specific operating range. Buyers connecting a pellet stove to an existing flue should confirm the liner diameter and material match the manufacturer's venting specifications.

Frequently Asked Questions

What is a wood stove venting kit?

A wood stove venting kit is a bundled package that includes a flexible stainless steel chimney liner and all hardware needed to reline a masonry chimney: top plate, storm collar, termination cap, and locking band. One order covers a complete installation.

What size chimney liner kit do I need for my wood stove?

Match the liner diameter to the stove's flue collar. Most wood stoves rated under 2,100 sq ft use a 6-inch collar. Check the spec plate on your stove before ordering. An oversized liner reduces draft by holding a column of cool air the stove cannot heat fast enough.

What is the difference between a chimney liner kit and a stove pipe kit?

A stovepipe kit covers the stove-to-wall connector inside the heated space. A chimney liner kit is the stainless steel liner running inside the masonry chimney from that connection to the termination cap at the roofline. Both are required for a complete installation.

Do I need an insulated chimney liner kit?

Only for exterior chimneys or runs through unheated spaces. An insulated chimney liner kit with rockwool wrap prevents the liner from cooling too fast and reduces creosote buildup in cold climates. Interior chimneys in a heated home do not need insulated liner.

Can I use a chimney liner kit for a pellet stove?

No. Pellet stoves require 3-inch to 4-inch PelletVent pipe, not the flexible liner in a standard chimney liner kit. PelletVent is engineered for pellet fuel's lower exhaust temperatures. Order a pellet stove venting kit rated for solid pellet fuel instead.
